Struct CcInvocation 

pub struct CcInvocation { /* private fields */ }

A parsed, admitted C or C++ compile.

Implementations

impl CcInvocation

pub fn parse(arguments: &[OsString]) -> Result<Self, CcBypassReason>

Parse a driver command line, admitting only modeled single-object compiles.

pub fn source(&self) -> &Path

Source file this invocation compiles.

pub fn output(&self) -> &Path

Object file this invocation produces.

pub fn include_dirs(&self) -> &[PathBuf]

Include search directories named on the command line, in order.

pub fn required_inputs(&self) -> &[PathBuf]

Files that must appear among the discovered inputs.

pub fn language(&self) -> CcLanguage

Language the driver compiles.

pub fn sysroot(&self) -> Option<&Path>

Sysroot named on the command line, if any.

pub fn source_name(&self) -> String

Short label used for timing statistics.

pub fn dependency_arguments(&self, depfile: &Path) -> Vec<OsString>

Arguments to append so the driver writes a dependency list beside the object.

-MD rather than -MMD: system headers are exactly the inputs most likely to change without any other key component noticing, because the compiler identity does not cover the C library or the platform SDK.

pub fn invocation_digest( &self, context: &CcActionContext, ) -> Result<CacheDigest, CcBypassReason>

Digest of the pre-input fingerprint, used to look up a prediction.

pub fn action( &self, context: CcActionContext, ) -> Result<CcAction, CcBypassReason>

Build the canonical action for this invocation and its discovered inputs.

pub fn prediction( &self, context: &CcActionContext, compiler_duration_ns: u64, ) -> Result<CcInputPrediction, CcBypassReason>

Record the normalized inputs of a successful compile so the next cold invocation can rebuild the same key before compiling.
